CORNER-CUTTER FOR PAPER BOX BLANKS.

SPECIFICATION forming part of Letters Patent No. 473,859, dated April26, 1892.

Application filed September 29, 1890. Serial No. 366,707. (No model.)

. blanks to be made into boxes.

My improved machine hasa cross-head provided with two different shapedknives.

My invention consists, essentially, in the bed and its attached plates,combined with the cross-head and its attached cutter-carriers and cutterto notch a blank, and adjustable corner-gages located on the same sideof the cutter and their holding-blocks, substantially as will bedescribed.

Other features of my invention will be pointed out in the claims at theend of this specification.

Figure 1, in elevation partially broken out, shows a corner-cuttingmachine embodying my invention. Figs. 2 and 3 are details to be referredto; Fig. 4., a view of the under side of the cross-head and its knives.Fig. 5 shows a plan view of the machine, with the bed, its gages, andthe stationary knives; and Figs. 6 and 7, parts of a blank, showingshapes of notches to be cut.

The frame of the machine consists, essentially, of legs A and a table orbed A, mounted thereon. From this bed rise guideways A in which isfitted to slide a cross-head B, to which is attached in adjustablemanner knife-carriers C and D. The knife-carrier C has attached to itadjustably a knife to, which is V- shaped and so placed as to cut anotch, as a, in the blank E. (Shown separately in Fig. 6.) Theknife-carrier D has attached to it a knife 17, the shape of thecutting-edge of which is as best represented in Fig. 4, it being adaptedto cut out from the corner of the blank a rightangled notch, (see Fig.7,) or to cut off the ends of the lip 20 left by the action of the V-shaped cutter a, as is desirable in the manufacture of some kinds ofboxes. (See dotted line, Fig. 6.)

The cross-head B has jointed to its lower end a link B, Which surroundsa crank-pin at the inner end of a rotating shaft B having suitablebearings in the frame-work, the said shaft having in practice mountedupon it a suitable belt-pulley B adapted to be driven by power from anysuitable source.

The bed-plate has slots h h W W, in which are made adjustable the blocksh h h h holding the guides m m m m which in practice are set in theproper position, according to the box to be made. Each block has a likelipnto enter a groove in the top of the guide and at their lower sidesprojections 11* (see Figs. 2 and 3) to enter the slots, which aid inguiding said blocks, each block being shown as held in adjusted positionbya bolt n, having a thumb-nut 72. The slots h h receive suitableprojections at the lower sides of the gages m m so that they are held inadjusted position by suitable bolts it, (see Fig. 5,) which correspondwith those marked n and adapted to hold the blocks h k in adjustedposition. These gages may be adjusted toward or from each other,according to the size of the blank to be cut. The bed-plate in practivewill have suitable steel plates, as a b fastened to or let into it, theyhaving their inner edges parallel to the cutting-edges of the cutters aand b, the said plates constituting the lower members of the cutters.These gages m and m are adjustable not only in the direction of theirlength, but also at right angles thereto by the blocks it 77.

The gages m and m constitute a pair and the gages m and an another pair,one pair of gages being used to position the blank when the edge nearone corner is to be provided with a diagonal or inclined notch a, (seeFig. 6,) the other pair of gages positioning the blank when a notch isbeing made in the same edge of the blank, but near its opposite end.

It is necessary to cut the notches (shown at a in Fig. 6) at an angle,and to insure this the gages m and m are inclined with relation to aline drawn through the machine from front to back and intersecting thecorner angles of the cutters; or, in other words, the

gages m m are set at right angles to the edge of the blade a nearest tothem.

The gages m and m are set at right angles to the faces, respectively, ofthe gages m and m I claim.-

l. The bed and its attached plates a, combined with the cross-head andits attached cutter-carrier C, and the cutter Ct to notch a blank, andwith the adjustable independent gage-holding blocks located at the sameside of the cutter, and the corner-gages m m each adj ustablelongitudinally in its holding-block, substantially as described.

2. In a machine for notching blanks, a crosshead, a cutter-carrier, andcutter, combined with the table, and the gages mm m m and adjustableholders in which they are made adjustable, substantially as and for thepurpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EUGENE H. TAYLOR.
